Application filed June 23,

To @ZZ whom t may concern.'

Be it known that I, VILLIAM H. BURNS, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented a new and useful Improvement in Hairpins, of which the following is a specification.

This invention relates to hair-pins; and the primary object is to provide an improved hair-pin capable of holding` the hair with great security, but capable, nevertheless, of being easily inserted and removed from the hair.

The invention is illustrated, in its preferred embodiment, in the accompanying drawing, which shows a plan view of the improved hair-pin.

As illustrated, the improved hair-pin comprises a loopelike head l and legs 2. rlhe loop l is preferably in the form of a conventional somewhat elongated arrow-head with rounded corners, the construction being such as to form a comparatively narrow throat 3. The members or arms 2 converge downwardly from the throat 3 and come into substantial contact at point 4, where they terminate in lingers which diverge as indicated at 2a, and then converge slightly, as indicated at 2b. rlhus, the ngers or extremities of the arms of the pin are separated by a space 5, while the main portions of the members 2 are sepa rated by a narrow downwardly-converging space 6. The head, or loop, l, affords an enlarged space 7.

The hair-pin is preferably formed of resilient wire of large enough gauge to afford the desired strength and resiliency.

When the pin is inserted in the hair, the somewhat narrow opening between the extremities of the members 2 serves to admit only a limited amount of hair between the members 2. This result is aided bythe fact that the portions 2b converge towards the extremities, so that the hair has a tendency to prevent the members 2 from separating widely. The lock of hair to be secured enters the loop 7, and with this will be included some of the hair close to the persons head which tends to hold the pin in position. Also, the hair close to the persons head which tends to hold the pin in position will be gripped between the members 2 throughout their length, and because of the convergency of these members an effective 1919. Serial No. 306,095.

so that, in effect, we have the hair which is within the hair-pin tending to expand the pin, while the hair which is outside the pin is tending to` compress the pin. Thus, the

pin secures a very effective hold upon the hair, Y

While it is preferred to employ resilient wire in the construction of the pin, any suitable resilient material ymay be employed.

What l regard as new, and desire to secure by Letters Patent, is:

l. As an article of manufacture, a hair pin comprising a rrelatively short spearhead shaped loopat one end having a constricted throat, a pair of relatively long converging resilient arms extending from opposite sides of the throat and terminating in a pair of fingers which flare outwardly from the arms and then converge to define an area approximately equal to the loop whereby the strand of hair initially embraced by the lingers will be compressed between the arms as vthe pin is inserted and iinally expand to fill the loop and lock the pin in fully 4inserted position.

2. As an article of manufacture, ahair pin having a relatively short loop at one end, one end of the loop being arc-shaped and connected to two divergent sides which terminate in two short sharply convergent ends spaced apart to form an open throat, a pair of relatively long converging arms, connected to opposite sides of the throat and terminating in a pair of fingers which flare outwardly from the arms and then converge, whereby the strand of hair embraced by the fingers will separate the arms as the pin is inserted, the arms fulcruming about the throat of the loop and the strand expanding to fill the loop and lock the pin in fully inserted position.

3. A hair pin formed from a single piece of material bent upon itself to form a relatively short loop having abrupt shoulders providing a constricted throat, relatively long arms extending from the throat and terminating in fingers having short outwardly flaring portions and relatively long converging tips. whereby as the pin is inserted the fingers will embrace a strand of hair, which will pass between the arms and expand to fill the loop and the fingers will ff i aegee be prevented from expanding as 'the pin is being insere-Cl by external pressure of *elle hair on the converging; tips.

1. hairpin comprieing an aj,.',xfo\.vhea& shaped loop having rounded corners and oonetrictecl at its base to provide a comparatively narrow throee arms extending outwardly `from opposite sides of Jshe throal and converging throughout a length of from two o rhree mines the length of the loop, the arme terminating in tips first flaring- 0utwarrlly and then converging Juhrouglwut a length substantially equal to the length of the loop and deiining an area approximately equal hereto.
